Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Success can never happen without the journey (struggle).

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

A book a day keeps the stupidity away.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

There are no bad mistakes in maths, only discoveries.

The easiest person to deceive is yourself.

You can hire a tutor but you can't hire someone to practice for you.

There is no elevator to success, you have to take the stairs.

The greatest mistake we make is living in constant fear that we will make one.

Never underestimate the importance of small steps. small steps = big changes. 

You're not in competition with anyone but yourself. Outdo your past, not other people.

He who has begun his task is half-way done. Have the courage to begin!

If you really want something you’ll find a way. If you don’t you’ll find an excuse.
